I have always thought very highly of your filters. I know you say every 3 months, but I think they would last longer because of how they are made. Thanks
I received my filters, different sizes, in time to replace the old & put these in. The first thing I noticed was they arent fiberglass, arent backed with metal, and didnt cause itching when handling, all the problems of other filters. Theyre installed and working great. Sizes are perfect, were easy to install & didnt fall out of ductwork when switching! Kudos, highly recommend!!
